That was no doubt an Oh CHIT!!!!! moment. Glad it didn't run into an Oh FLUCK moment.

That's the pass I was telling you about.

I guess we should name it "The Pass in the Grass"...

:icon18: was sure in the grass it's a good thing nothing was damaged could have been a lot worse.

Talked with Mark at Mazworx. He seems to think the FI exhaust manifolds are good for 500hp a side without too much of an issue. He has a set in his hands right now getting ready to port match them for someone else. He did suggest upgrading to tubular manifolds would be best.
The room to make it happen is limited. Phunk is the only one that has made it happen. I am not sure if he will ever make anymore again. I guess we shall see where I end up.

New Intake pipes from filter to turbo will be made next week. Going from 2.5in to 3in. to match the intake size of the turbo.

This makes sense some GTR guys are using tubular manifolds with the same size turbos you have along with 3.5 inch down pipes.

Can you find out what AR they are running on the hot side please.

It is kind of crazy where we have ended up. All the great things in the past we really needed we couldn't use because nobody could keep the heads sealed up. Now, that issue has been figured out we need some of these parts and pieces to come back.

I don't think I ever posted my interim dyno graph. Give me a few and I will.

I believe you are going to find that the FI manifolds will take you where you want to go! When you are looking at a part that flows... whether its fuel system, cylinder head, exhaust pipe, intercooler, throttle body. Remember that there is no airflow/fuel-flow limit to any one of these components. As flow goes up, pressure will go up. Pressure drop across the A to B increases. Efficiency starts to degrade, but it never hits a wall and just stops. This is why the duration/length of a restrictive cross-section is equally important as the cross-section size itself.

As for the GT-R community.. look at the stock turbo manifolds for the GTR. They are integrated to the turbine housing (excluding 2020+ where they separated manifold and housing). People are upgrading the stock turbos from mild to wild, anything from just changing out the wheels on the stock CHRA and machining clearance in the housings, all the way to welding up the CHRA area to put in much larger turbos... and making 1200+ whp through the stock manifolds with stock internal wastegates (upgraded actuators). Those are some small manifolds!

As for CJM manifolds... I have been too busy to mess around much with fabricated products the last 2 years since I am not efficiently configured for that type of product. But I believe I did mention to you that I am in talks with someone who has been prototyping some cast stainless manifolds for the VQ that should meet your needs easily. I dont have a timeline nailed down with him but it sure looks like its close. Unless he falls off the earth I feel like he will have them done before the new year, if not any day now.

Interim, work in progress. Ethanol Content was 75% with Ignite Red.

Dyno Graph looks great. If we can get the IAT's under control it will look much better.

Nice! Is power dropping off early due to high IAT's

That or hitting the turbos limits. IAT's of 152 deg. F did not help.

Bringing in this back for comparison. This was on Ignite Red with Ethanol content of 85%.

Hopefully it's IAT'S and the new ic fixes that. It'll easily hit 1000whp

Ethanol content was only 75%. With 85% it will have more also. My old dyno graph was at 85%. It is full to the brim in the tank. Not too worried about that. Let Nick finish it on that. At 87% it will be even more.

At 92 deg. ambient, which is hot as heck, it actually is really good. With all that working against me I am still happy with it. If I can make the same power on only 28psi of boost and Ignite Red content of 75% I will be happy.

Picture of the FI intercooler. Notice how the end caps slope down to the center. This is the problem. Need to flow the same volume of air from the 2 1/2in. diameter pipe across the whole core. Notice how it only appears to have enough volume until half way and then it really get's bad. Everything that I have read says this is a problem with the endcaps. Anywhere that the air has to speed up will create heat and a pressure drop. I guess we shall see if that is correct or not.

Sorry if my car is a little too dirty for you. I drive my car. It is not a garage queen that I polish and look at. It is a tool for me to have fun. I grew out of the Mr. Clean status years ago.

I think I shared this before. My issue is no where near as bad as this but the concept is the same. An acceptable pressure drop is only 1 psi.
You also have to remember I didn't start having any issues until I got to 25psi of boost. At that level the IAT's started to climb. It got way out
of whack at 30psi of boost.

Ready to go out and get some Draggy times. Tired of doing nothing. I am ready to go do something.

Already have my first ride along victim lined up. He can't wait to go for a ride. LOL

Food for thought.

Looking back over your previous 12,17,25# graph, unsure if I’ll be tuning much over 20# :ugh2:
That’s with built 7A/T & wanting it to live for a while + be able to learn the different power levels & focus on getting traction through the lower gears :driving:
What you’re building is a Monster :eek::iagree::eek:

Just throw a th400 in there and call it good. :happydance:

Slush Box.... Uck!!!!

I just signed up for Z Nationals. I am not doing the track day. I forgot to sign up and they are full. I promised my nephew I would come hang out so I figured we would go to Z Nationals and have a blast.

I thought real hard about going to FL2K to do some roll racing. My input shaft would not survive on a prepped track more than likely. If I broke the car so quickly my wife would kill me. So, Z Nationals it is this time.

Car is supposed to finish up this week and dyno time to finish the tune will be next week. We shall see if it makes it. I sure miss it. I got my fingers crossed.

Moving on along at a steady pace. No worries from me. Ready to have some fun.

Next week? Next month? Next year?

Next Whenever...... This week or next week. LOL

Yeah, deadlines are pretty darn hard to follow. I've learned that forward progress of any sort is good progress.

Still patiently waiting but time is getting short. I got places to go and things to do.

Should be back on the dyno next week if all goes as planned. I can't wait to see what we get and how the new intercooler does.

This is going to be epic time to awaken the beast

I hope so. Got my fingers crossed.

Once you blow a headgasket it is always in the back of your mind that it might happen again. I am pushing the crap out of this engine and turbo setup. The excess back pressure from the turbo's tight AR can cause issues. I am just hoping I was dropping 5 to 6 psi of boost at the intercooler. That will give me the headroom I need to run a good number without a turbo change. I want usable power, not some dyno number. Nick will do his best. I know I am on the limit and things can go wrong at this power level real quick. So yeah, I am stressing some. If the chit goes south, I will send the motor back to Mazworx and make a turbo AR change.
